Hello there. I am trying to install the ATI drivers on Linux Mint 13 x64 and I get this error when I attempt to install the packages from the repositories for my distribution. I previously tried to install the drivers from the binary installer I got from the ATI website and that did not work. I am attempting to install the driver packages from the Linux Mint repositories and having no luck.

[Warning] Uninstall : inst_path_default or inst_path_override
does not exist in /etc/ati. This suggests that the AMD driver
is not installed, the AMD driver is only partially installed,
or the current AMD driver installed is an older version than the
one this script was designed for. Both files listed above are
required for determining where installed files are located.
To force uninstallation of the driver by guessing where the
uninstallation files are located, set the force option
re-run /usr/share/ati/fglrx-uninstall.sh (this is not recommended).
